Salvia plant named ‘Silver Sabre’

ABSTRACT

A new and distinct form of  Salvia  plant characterized an evenly white, variegated margin, a low, well-branched habit, and excellent vigor.

Botanical denomination: Salvia officinalis.

Variety designation: ‘Silver Sabre’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Salvia, given the name, ‘Silver Sabre’. Salvia is in the family Lamiaceae. This new cultivar was found as a branch mutation of Salvia officinalis ‘Tricolor’ (unpatented). Compared to Salvia officinalis ‘Tricolor’ the new cultivar has a lower, more branched habit due to compressed internodes, and more evenly white marginal variegation. The new cultivar exhibits the pink new growth of the parent plant.

SUMMARY OF THE INVENTION

This plant exhibits the following characteristics that make it unique:

-   -   1. an evenly white, variegated margin,     -   2. a low well-branched habit, and     -   3. excellent vigor.

The new variety has been reproduced only by asexual propagation (stem cuttings and micropropagation). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and micropropagation as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
